Cookie not retrieving as it should in some cases

[Ferrous Cranus]

# retrieve cookie from client's browser otherwise set it
try:
cookie = cookies.SimpleCookie( os.environ.get('HTTP_COOKIE', '') )
cookieID = cookie['ID'].value
except:
cookieID = str( time.time() )
cookieID = cookieID[-3:]

cookie['ID'] = cookieID


Many times i noticed that the script instead of retrieving the cookie ID value so to identify each visitor uniquely it insteads set its again.
The same think also happens when someone comes to superhost.gr via a link from anothwe webpage

can somebody tell me why this is happening?
is there some flaw in my code? Perhaps it can be written more efficiently?

I had a similar issue when using Beaker middleware for WSGI which was
caused by me not specifying a location for the storage of the cookie
database.

I have tried also to set the path of the cookie and the expiration date of the cookie so for them not to impose a problem but yet the situation remains the same.

# retrieve cookie from client's browser otherwise set it
try:
cookie = cookies.SimpleCookie( os.environ['HTTP_COOKIE'] )
cookieID = cookie['ID'].value
except KeyError:
cookieID = str( time.time() )
cookieID = cookieID[-3:]

cookie['ID'] = cookieID
cookie['ID']['path'] = '/'
cookie['ID']['expires'] = 3600 * 24 * 365 # 1 year from now
print( cookie.output() ) # send cookie to web client before headers

The cookie is properly set in my Chrome browser as i see form Chrome settings.

If someone visits for example ypsilandio.gr and then clicks superhost.gr from there then another cookie is also set with the same name 'ID' cusing a mess to the database hwich iam storing the visitor's based on the cookie i'am tryign to retrive from them.
